With a record number of people living to well over 100, Michael Nicholson investigates the life extension industry now worth millions of pounds. He seeks the truth behind claims that the human race is on the verge of increasing life span beyond 1000 years through advances in medical science. He meets those investing their hard earned cash into products and lifestyles which claim to extend lifespan and good health - from a man who takes 50 supplements a day, to one of Europe's richest men investing millions into scientific research aimed at stamping out old age forever. The programme also uncovers the black market in growth hormone, a treatment peddled by some internet sites as the way to beat the ageing process.
